细叶亚马尼亚的基本数据

养护难度

适合中级者

寿命

多年生植物。通过修剪可长期维持

体型

高度20-50厘米，宽度12-20厘米

适宜温度

22〜28℃

浇水

CO2添加及硝酸盐、磷酸盐、铁质肥料施肥

光照强度

需要中等至强光。光越强，红褐色越深。

CO2和肥料

建议进行CO2添加（约25-30毫克/升）。控制硝酸盐，增加磷酸盐和微量元素可使颜色更深。缺铁时叶片褪色。

水温和水质

适宜温度为22-28℃。喜欢弱酸性软水（pH 5-7.5），但能在一定程度上适应。

底床和固着

由于植株较大，应在76升以上的水族箱中景或后景中种植。

修剪和繁殖方法

当生长到水面时，剪去顶部并重新种植。也可以通过切分侧枝进行繁殖。

注意事项

植株较大，不适合小型水族箱。水草不应扔到野外，不应逸出到水族箱外。

关于细叶亚马尼亚

Ammannia gracilis is a stem plant that turns reddish-brown under strong light. This large 20-50cm perennial suits the mid- to background of aquascapes and can be maintained long-term through trimming and replanting.

开始养护细叶亚马尼亚前需要了解的7件事

1. 1Give It Strong Light

   Bright lighting is essential for bringing out Ammannia gracilis's signature cognac-red color. Under weak light it tends to stay green and grow leggy, so place it where light reaches well.

2. 2Plant Mid to Background

   This is a large plant, growing 20-50cm tall and 12-20cm wide, so it looks best planted in groups toward the middle or back of the tank rather than up front. Tanks of 76 liters or more give it room to show its full form.

3. 3Use Nutrient-Rich Substrate

   Because it grows so large, this plant has fairly high nutrient demands from its roots. A nutrient-rich substrate combined with root tabs helps keep leaf color and stem thickness consistent.

4. 4Trim and Replant Cuttings

   As a perennial, overgrown stems can be cut and replanted to keep the plant going indefinitely. Regular trimming both shapes the plant and rejuvenates it.

5. 5Choose Compact Nodes

   Look for a plant with tightly spaced leaf nodes and a sturdy stem, which establishes more easily. Leggy, stretched-out specimens can take longer to regain their proper form once settled in.

6. 6CO2 Boosts Coloration

   This is considered an intermediate-level plant, and growth and coloration tend to be more stable with CO2 injection. It can survive without CO2, but the reddish coloring is harder to achieve and the plant is more prone to legginess.

7. 7Keep Temperature Stable

   Sudden swings in water temperature can damage or drop leaves. Use a heater or chiller as needed through seasonal changes to keep conditions steady and avoid stressing the plant.

细叶亚马尼亚的常见问题

Q.Is this plant suitable for beginners?

A.Ammannia gracilis is considered an intermediate-level plant. It needs a bit more attention to lighting and CO2 than easier species, so it's a good next step once you're comfortable with basic stem plants.

Q.Why does it stay green instead of turning red?

A.The main cause is insufficient light. Providing strong lighting for a sufficient duration each day helps bring out the cognac-red coloration.

Q.What tank size does it need?

A.Since it can grow 20-50cm tall and 12-20cm wide, it's best suited to the mid- to background of tanks 76 liters or larger. Smaller tanks can feel cramped for a plant this size.

Q.What should I do if it grows too tall?

A.Cut the top of the overgrown stem and replant it in the substrate as a cutting. Since it's a perennial, repeating this process lets you maintain it indefinitely.

Q.Is CO2 injection required?

A.It's not strictly required, but growth and coloration tend to be more stable with CO2. Without it, the plant is more prone to legginess and weaker red coloration.
